The Bosch Rexroth Z2FS16-8-3X/SV (R900470529) is a high-performance industrial hydraulic valve designed for precise flow control in hydraulic systems. This valve is of the ZFS type, which is a throttle check valve in a sandwich plate design, suitable for limiting the flow to one or two actuator ports with high reliability. It features a spool symbol A A, B B or A A, B B, indicating that it can be configured for different circuit designs.
This direct-actuated valve allows for accurate throttling to a set value and features a spindle with an internal hexagon for adjustment. The mechanically actuated throttle check valves are equipped with symmetrically arranged throttle spools that limit flows in one direction while permitting free return flow in the opposite direction. This ensures smooth operation and precise control over the fluid dynamics within the system.
The Z2FS16-8-3X/SV has been engineered to handle maximum pressures efficiently and comes with FKM seals which are compatible with various hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. It also conforms to NFPA T.. R D and ISO porting patterns for easy integration into existing systems.
With its robust design and versatile capabilities including meter-in or meter-out throttling options, this Bosch Rexroth valve is an essential component for applications requiring precise actuator velocity adjustments. The valve's maximum operating pressure stands at bar while it can accommodate a maximum flow of l/min. Its sandwich plate configuration ensures that it can be easily mounted between directional valves and subplates within complex hydraulic circuits.
Overall, the Bosch Rexroth Z2FS16-8-3X/SV (R900470529) represents a reliable solution for sophisticated hydraulic control tasks where precision and durability are paramount.

The valve type Z2FS is a throttle check valve in sandwich plate design. It is used for the flow limitation of one or two actuator ports.
Two symmetrically arranged throttle check valves limit flows (by adjustable throttle spools) in one direction and allow free return flow in the opposite direction.
In case of supply throttling, the hydraulic fluid is directed through channel A➀ via throttling point (1) to actuator A➁. The throttle spool (2.1) can be axially adjusted via the spindle (3) for adjustment of the throttling point (1).
Simultaneously, the hydraulic fluid in channel A➀ is directed via the bore (4) to the piston side (5).
The active pressure and the spring force retain the throttle spool (2.1) in throttle position.
The hydraulic fluid return flow from actuator B➁ displaces the throttle spool (2.2) and enables the unobstructed flow as check valve. Depending on the version ("S" or "S2"), the throttling effect may occur in supply or discharge.
Flow limitation
For actuator velocity adjustment, the throttle check valve is installed between the directional valve and the subplate.
